Figure 4.
Signals (RLU, mean ± SEM) detected by the device for (A) rat RBC, (B) rat feces, (C) mouse urine, and (D) cervical epithelial cells. There was a strong linear correlation for detection of all rodent samples (R2 = 0.9943, R2 = 0.7629, and R2 = 0.8870, respectively). In contrast, the signal from epithelial cells did not correlate with cellularity. ND, no detection of ATP at this concentration.
